OBJECTIVES: This study reviews 9 patients with aortico-left ventricular tunnel (ALVT) and aims to establish the optimal surgical strategies for this exceptional and rare pathology. METHODS: 54,882 patients underwent open-heart surgery at the Fuwai Hospital between July 1996 and May 2008. Nine of these patients were diagnosed with ALVT. One patient died of acute heart failure before operation. The remaining 8 patients underwent operation. The mean age of these 8 patients was 22.5 years. Clinical, echocardiographic and surgical details were reviewed. RESULTS: At operation the diagnosis was confirmed, and then repaired by direct suture closure (n = 1), single patch closure of the aortic end of the ALVT (n = 4), or aortic valve replacement (n = 3). In 5 patients, the aortic opening of the tunnel was above the right coronary sinus of Valsalva while in the other 3 it was above the left coronary sinus. All patients recovered safely. There was 1 late death (from perivalvular leak). The remaining patients remain asymptomatic at a mean follow up of 30.1 months. CONCLUSIONS: ALVT is a rare cardiac entity that should be treated soon after the diagnosis is made. The specific surgical operation should be individualized based on unique cardiac anomaly of each patient. Copyright 2009 S. Karger AG, Basel.
